SPOT Beacons Interfere with GPS 175

 I have a bit more testing to do but it appears I have figured out the intermittent interference with the GPS 175.  Spot beacons transmit on a similar frequency and can blank out the satellite signals.  So every five minutes the gps loses its satellites for 10 to 20 seconds.  This is exactly what I am experiencing.

This is a great relief and I look forward to some test flights!
